Description of the Invention: [Technical Field of the Invention] The present disclosure relates generally to a decompression medical system, and more particularly, but not by way of limitation, to the use of an isolated fluid path for measurement. Pressure system and method. The present invention claims the benefit of 35 applications under § 119(e) of the following US Provisional Patent Application: filed on May 18, 2010 and entitled "Systems and Methods for Measuring Reduced Pressure Employing An Isolated U.S. Provisional Patent Application Serial No. 61/345,830, the disclosure of which is incorporated herein by reference in its entirety in its entirety in its entirety in its entirety in U.S. Provisional Patent Application Serial No. 61/345,821, the disclosure of which is incorporated herein by reference in its entirety in its entirety in -Pressure Canisters and Methods for Recycling, US Provisional Patent Application Serial No. 61/414, 738, which is incorporated herein by reference in its entirety. [Prior Art] Clinical studies and practices have shown that providing reduced pressure near a tissue site enhances and accelerates the growth of new tissue at the tissue site. This phenomenon has a wide range of applications, but the application of reduced pressure can be particularly successful in treating wounds. This treatment (often referred to as "negative pressure wound therapy", "reduced pressure therapy" or "vacuum therapy" in the medical community) provides for rapid healing and promotion of granulation tissue formation. 156368.doc 201200178 Benefits β often' The reduced pressure is applied to the tissue via a porous pad or its (iv) fluid device. The porous pad contains cells or pores that are capable of distributing reduced pressure to the tissue and directing fluid that is not taken from the tissue. Sometimes, it may be desirable to determine the decompression involved at the organizational level. For example, it may be desirable to determine that the reduced pressure is within a therapeutic range. SUMMARY OF THE INVENTION According to an illustrative, non-limiting embodiment, a system for treating a tissue site on a patient by decompression comprises: a therapeutic introducer for deployment at a location proximate to the tissue; a sealing member for forming a fluid seal over the portion of the 'oral therapeutic fluid and one of the patient's skin; a reduced pressure source for providing reduced pressure; and a reduced pressure delivery conduit for fluid light The therapeutic introducer fluid is brought to the reduced pressure source. The reduced pressure delivery catheter is used to deliver a therapeutic reduced pressure to the therapeutic introducer. The system advancement includes a reduced pressure assessment catheter and an evaluation chamber for fluid coupling to the ankle tissue site. The evaluation chamber is for fluid coupling to the reduced pressure assessment catheter and for receiving an assessment decompression from the tissue site. The evaluation chamber includes a sealed enclosure having a first movable portion on a wall. The first moveable portion is operable to move under the influence of reduced pressure.

To avoid detail not required to enable those skilled in the art to practice the embodiments described herein, the description may omit certain information known to those skilled in the art. The following detailed description is not to be considered as limiting, and the scope of the illustrative embodiments Referring to the drawings and mainly to Figs. 1 and 2', a system for treating a tissue site i 〇 2 on a patient by decompression is presented. The system 〇 〇 includes two dressings 104, a decompression subsystem 106, and a decompression evaluation subsystem 1〇8. The reduced pressure subsystem 108 allows for the evaluation of the reduced pressure at the tissue site 1〇2 relative to the pressure level while avoiding exposure of the high value components to the contaminated fluid, which may be a liquid or a gas. As used herein, "or" does not require mutual exclusivity. The tissue site 102 can be any body tissue of a human, animal or other organism, including bone tissue, adipose tissue, muscle tissue, dermal tissue, vascular tissue, connective tissue, cartilage, tendon, ligament or any other tissue. Fluid contaminants may include, without limitation, proteins, volatile organic compounds (VOCs), fatty acids, amines such as putrescine and crotonic acid, and other contaminants. The reduced pressure evaluation subsystem 1 〇 8 will work with any orientation relative to the gravitational field' because the pressure acts in all directions. The dressing 104 includes a treatment fluid 11 〇 and the treatment fluid 1 〇〇 is placed close to the tissue site 1 〇 2 . A drainage system-material or structure that is provided to assist in the application of reduced pressure to a tissue site 1〇2, to deliver fluid to a tissue site 102, or to remove fluid from a tissue site 102. The treatment introducer 110 typically includes a plurality of flow channels or passages that are distributed to provide a tissue site 102 in the region adjacent to the therapeutic fluid 110 and a tissue site in the region adjacent to the therapeutic drainage fluid 110 from the treatment 156368.doc 201200178 Remove the fluid. In one illustrative embodiment, the flow channels or passages are interconnected to improve the distribution of fluid provided to or removed from the tissue site 102. The treatment drain 110 can be a biocompatible material that can be placed in contact with the tissue site 1〇2 and dispensed under reduced pressure to the tissue site 1〇2. Examples of treating a fluidic channel can include, by way of example and not limitation, structural elements that are configured to form a flow channel (such as, for example, a honeycomb foam, an open cell to a foam, A device for collecting porous tissue, a liquid, a gel, and a foam comprising or curing to include a flow channel. The treatment introducer fluid can be porous and can be made of a foam, gauze, charm pad or any other material suitable for a particular biological application. In an illustrative, non-limiting embodiment, the treatment fluid is a porous foam and includes a plurality of interconnected cells or pores for use as flow channels. The porous foam may be a polyurethane, an open cell, a reticulated foam such as the GranuFoam® material manufactured by Kinetic Concepts, Incorporated of San Antonio, Texas. In some cases, the therapeutic introducer 11 can also be used to dispense fluids (such as drugs, antibacterials, growth factors, and various solutions) to the tissue site 102. Other layers, such as absorbent materials, wicking materials, hydrophobic materials, and hydrophilic materials, may be included in or on the treatment fluidic raft. The dressing 104 further includes a sealing member 12 that covers the treatment fluid guide and one of the skins 114 of the patient. An attachment device 116 can be used to help form a fluid 156368.doc 201200178 seal between the closure member 112 and the patient's skin 114. The minus 1 interface 118 can extend through the sealing member ι 2 to provide fluid access to the therapeutic priming fluid 110. The particular reduced pressure source or sub-system involved is given. This fluid seal is sufficient to maintain a reduced pressure at a desired location. The sealing member 112 can be any material that provides a fluid seal. The sealing member 112 can be, for example, but not limited to, a (four) or a semi-fourth elastomeric material. Examples of the elastomer can include, but are not limited to, natural rubber, polyisoprene, styrene butadiene rubber, chlorine. Butadiene rubber, polybutylene dilute, nitrile rubber, butyl rubber, ethylene propylene rubber, EPDM rubber, chlorine-based polyethylene, polysulfide rubber, polyamine formic acid, EVA film, copolymerized vinegar and Additional examples of sealing component U2 include polyoxynized wipes, 3M Tegadenn 8 wipes, acrylic wipes such as those available from Avery Dennison, Pasadena, California. Attachment devices can be used The sealing member 112 is held against the patient's skin 114 or another layer, such as a pad or additional sealing member. The attachment device 116 can take several forms. For example, and without limitation, the attachment device 116 A medically acceptable pressure sensitive adhesive or a hydrocolloid may be stretched around the periphery of one of the sealing members 112. The reduced pressure generated by the reduced pressure subsystem 106 is delivered to the reduced pressure via a reduced pressure delivery conduit 120. Interface 118. In one description In an embodiment, the reduced pressure interface 118 is commercially available from KCI, San Antonio, Texas, as one of the TRAC pads or Sensa TRAC®. The reduced pressure interface 118 allows for reduced pressure delivery to the therapeutic approach fluid 1 . The reduced pressure interface 118 is also typically fluidly coupled to a reduced pressure evaluation conduit 122, which may be subjected to a plurality of reduced pressure evaluation conduits. 156368.doc 201200178 = Pressure-f estimate guide 122 allows delivery of tissue site 1 (10) reduction Pressed for the purpose of use. As shown clearly in Figure 2, the reduced pressure delivery conduit 12G and the reduced pressure gauge: the ancient conduit 122 may be combined into a combined guide 124 over some or all of its length. Figure i and Figure 2 In the embodiment shown, the distal end of the combination catheter m is depleted to the reduced pressure interface 118 and received from the tissue site 102 (the proximal end 128 of the group 0 catheter 124 can be fluidly coupled to a connector. A portion 132 of the delivery guide 120 is fluidly coupled between the connector 130 and a fluid reservoir 134. One of the proximal ends 133 of the reduced pressure delivery conduit 12 is fluidly coupled to the fluid reservoir 134. One portion of the reduced pressure assessment conduit 122 is 136 fluid Coupled to connector 13〇 and reduced pressure evaluation subsystem Between ι 8 ◎ a proximal end 137 of the reduced pressure evaluation catheter 122 is fluidly coupled to the evaluation chamber 146 and may include a hydrophobic filter 149. The reduced pressure subsystem 106 delivers reduced pressure to the dressing 丨〇 4. Subsystem 1 〇6 includes a reduced pressure source 138 that provides reduced pressure. The reduced pressure source 138 is fluidly coupled to fluid reservoir 134 by a second reduced pressure delivery conduit 140 to deliver a reduced pressure ι 42 or therapeutic reduced pressure 142 to the fluid. Reservoir 134. The reduced pressure source 138 can be used to supply any means of decompression, such as a vacuum pump, wall sink or other source. Although the amount and nature of decompression applied to a tissue site will generally vary depending on the application, the decompression will typically be between _5111 «11^(-667 ? &) and -500 mm Hg (-66.7 kPa) Between and more typically between -75 mm Hg (-9.9 kPa) and -300 mm Hg (-39.9 kPa). The decompression system is undergoing treatment at one of the tissue sites at a pressure less than one of the ambient pressures. In most cases, this decompression will be less than the atmospheric pressure at the patient's location. Alternatively, the reduced pressure can be less than, and the fluid at the weaving site is static. 156368.doc • 10· 201200178 Pressure. Unless otherwise indicated, the numerical pressure values described herein are gauge pressure. The reduced pressure delivered can be constant or varied (patterned or randomly varying) and can be delivered continuously or intermittently. Although the terms "vacuum" and "negative pressure" may be used to describe the pressure applied to a tissue site, the actual pressure applied to the tissue site may be greater than the pressure typically associated with a full vacuum. Consistent with the use herein, an increase in depressurization or vacuum pressure generally refers to a relative decrease in one of the absolute pressures. The reduced pressure subsystem 106 includes a reduced pressure source 138 that delivers a reduced pressure 142 to the fluid reservoir 134. The therapeutic decompression 142 is delivered to the knife 132 of the reduced pressure delivery catheter 12 . The therapeutic decompression is then delivered to the therapeutic introducer fluid 110 via the reduced pressure interface j丨8. The reduced pressure interface 118 can receive fluid 144 from the tissue site 1〇2, which is delivered by the reduced pressure delivery conduit 120 to the fluid reservoir 134. The portion 136 of the reduced pressure assessment conduit 122 delivers an evaluated reduced pressure to the reduced pressure assessment subsystem. 1〇8. The decompression is transmitted from the decompression interface 118 or the tissue site 1〇2 for decompression for measurement purposes. The reduced pressure evaluation subsystem 包括8 includes a self-decompression evaluation catheter 1 接收 receiving an evaluation reduction house-evaluation chamber 146. A hydrophobic filter 149 can be placed at the inlet of the pressure reduction ramp 122 into the evaluation chamber 146. The hydrophobic transition 149 system helps prevent fluid from entering the evaluation chamber 丨46. The plenum chamber 146 includes a sealed enclosure 148. The sealed enclosure 148 includes a wall 15A having a first movable portion 152, such as a first partition 154. The first movable portion can undergo a mixed phase, such as a gas and a liquid' without compromising accuracy. Typically, the first separator 154 is a half flexible material sheet which contains a black matrix. The periphery 156 of the tanzanite piece is anchored to the wall 150. The first baffle 154° operates to move at least slightly from the neutral position to the 156368.doc 201200178 β leveling chamber 146 within a displacement position under the influence of reduced pressure. The sealed enclosure ι48 may include an vent in some embodiments to allow gas from the tissue site to be vented to the atmosphere. A first pressure detector 158 is located proximate to the first moveable portion 152 and is operable to sense movement of the first moveable portion 152. The first pressure detector 158 is fluidly isolated from the evaluation chamber 146. Fluidly isolating the first pressure detector 158 from the evaluation chamber 146 means that contaminants in any gas or liquid that reaches the evaluation chamber 146 will not reach or contaminate the first pressure detector 丨58. The first pressure detector 158 can be included in an isolation chamber or housing. As will be explained in more detail below in conjunction with FIGS. 4A-8B, the first pressure detector ι 58 may use a Hall effect sensor, a capacitive sensor, an ultrasonic sensor, an infrared sensor or Other devices that detect the movement of the first movable portion 152. The reduced pressure evaluation subsystem 108 is operable to receive an estimated reduced pressure, and the estimated reduced pressure will move the first movable portion 152 inward from a neutral position to a displaced position upon reaching a sufficient level. The first pressure detector 158 senses the position of the first movable portion 152 and is capable of providing an indication of one of the relative changes in decompression. This change in the reduced pressure can be calibrated based on an initial measurement to reflect the reduced pressure experienced at the tissue site 102. The first pressure indicator ι 58 can present an indication of a relative change on the indicator 162 or provide a signal for further processing or use. In operation in accordance with an illustrative embodiment, the treatment introducer is placed adjacent to the tissue site 102. The sealing member 112 is deployed using the attachment device 116. Thus, a fluid seal is formed between the sealing member 112 and a portion of the patient's skin 156368.doc -12- 201200178 114. The reduced pressure interface 118 can be applied via one of the apertures 117 in the sealing member i i 2 if not already installed. The reduced pressure delivery conduit 120 and the reduced pressure assessment conduit 122 can be fluidly coupled to the reduced pressure interface 118 if not already coupled. Alternatively, as shown, the combination conduit 124, including one of the reduced pressure delivery conduit 120 and the reduced pressure assessment conduit 122, can be fluidly coupled to the reduced pressure interface 118. The reduced pressure delivery catheter 120 fluid is caked to the fluid reservoir 134. The reduced pressure source 138 is fluidly coupled to the fluid reservoir 134 to provide a reduced pressure to the fluid reservoir 134. Once activated, the reduced pressure source 138 will deliver reduced pressure to the fluid reservoir U4 via the reduced pressure delivery conduit 120 and to the tissue site 102. The fluid will typically move into the reduced pressure delivery conduit 12 and will flow to the fluid reservoir. 134. The reduced pressure interface 118 allows for the transfer of reduced pressure at one or more sampling sites to one or more of the reduced pressure assessment conduits 122. The reduced pressure evaluation catheter i22 delivers the estimated reduced pressure to the evaluation chamber 146. As previously described, after a sufficient level is reached, the reduced pressure moves the first moveable portion 152 of the sealed enclosure 148 from a neutral position inwardly to a displaced position. The displacement of the first movable portion 152 can be detected or sensed by the first pressure detector 158 and can be indicated or provided by the indicator 162 for the decompression - for processing (including the display factory) The force detector 15 8 can be adapted to provide a control signal to the reduced pressure source 138 to provide feedback control to maintain a desired pressure or desired pressure range. The reduced pressure evaluation subsystem 1 8 may also include a user interface such as a keypad and display to allow for typing of the desired range or receiving other control systems 100 and, in particular, the reduced pressure evaluation subsystem 108 is allowed Existence of gas 156368.doc •13· 201200178 In the case of body or liquid contamination, the pressure is estimated relative to the pressure. The reduced pressure S leveling subsystem 108' can be made such that the evaluation chamber 146 is made of relatively inexpensive components so that it is convenient to allow the evaluation chamber 146 to be disposed of after use, while allowing the first pressure detector 158 to be used again without contamination. risk. In this manner, the reduced pressure assessment subsystem 108 minimizes the chance of exposure of contaminated fluids to higher value items or relatively expensive components. Referring now primarily to Figure 3, there is shown another illustrative, non-limiting embodiment of a reduced pressure subsystem 2〇6 and a reduced pressure evaluation subsystem 208. 3 is a graphical cross-sectional view. In this illustrative embodiment, decompression subsystem 2〇6 is combined with decompression evaluation subsystem 208 into a reduced pressure treatment unit 209.

The first portion 264 and the second portion 266 can be held in close proximity to one another by an integrated housing or by a bracket 268 or other device. In this illustrative embodiment, reduced pressure source 238 delivers reduced pressure 242 to one of the pilots 270, a conduit 270 that delivers the reduced pressure to a fluid reservoir 234. The reduced pressure 242 is delivered to another conduit 272 that delivers the reduced pressure 242 to a connector 230. The connector 23 递 delivers the reduced pressure to a reduced pressure delivery catheter (not explicitly shown) that is part of a combined catheter 224. The combined catheter 224 delivers the reduced pressure to the tissue site. The second portion 266 of the reduced pressure treatment unit 209 includes a pump control unit 274 that provides pump energy to the mass of the reduced pressure source 238 using a link interface 276.

The first pressure detector 258 is fluidly isolated from the evaluation chamber 246. The first movable portion 252 is moved inward from a neutral position to a displacement position under reduced pressure. The first pressure detector 258 is operable to sense the displacement of the first movable portion 252 under the influence of the decompression and to change one of the decompressions on an indicator or by a signal. Therefore, the first pressure detection The detector 258 is operable to assess the level of pressure at the tissue site. The fluid reservoir 234 can include a wall 280 having a second movable portion 282, such as a second partition 284. Under the influence of the reduced pressure, the second movable J knife 282 can be displaced from one of the neutral positions into the fluid reservoir 234. A second pressure detector 286 can be included in the first portion 264 and can be substantially aligned with the first movable portion 282.

The isolation chamber 260 can include one or more exhaust ports and can further include a power unit 288' such as a battery that can provide electrical energy to various components, such as the pump control unit 274, the first pressure detector 258. And a second pressure detector 286. Additionally, the first portion 264 can include a user interface that receives an input, such as a desired pressure. The first portion 264 can include an indicator (not shown) for visually indicating pressure in the tissue or fluid reservoir 234. It should be noted that in the case of reduced pressure treatment unit 2〇9, a high value component that may be expected to be re-used is located within first portion 264 and is isolated from a portion of the second portion 266 that is contaminated or potentially contaminated. In the illustrative non-limiting embodiments presented herein, several combinations of components can be used to sense the displacement of the movable portions 152, 252, 282. A number of illustrative, non-limiting embodiments for sensing displacement will now be presented. Referring now primarily to Figures 4A and 4B', a portion of the reduced pressure evaluation subsystem is presented.

One of the inductances can be measured to change and used to determine the displacement of the first movable portion 352. For example, as the flux decreases, we know that the decompression has increased and the displacement of the first-movable portion 352 can be calibrated to indicate the pressure assessed internally to 346 relative to atmospheric pressure. A pressure change or pressure may be displayed on an indicator 362 or a signal may be sent for further processing (including display at another location).

The wall 55A includes a first movable portion 552, such as a first partition 554. The first baffle 554 includes a target and a flexible or semi-flexible perimeter 557. The target 555 on the first movable portion 552 includes a ferrite magnet or other material that can be sensed by a capacitive sensor 596. A first pressure detector 558 can be located proximate to the first moveable portion 552 and fluidly isolated from the evaluation chamber 546. The first pressure detector 558 can be within a compartment 560 or housing. In this illustrative embodiment, the first pressure detector 558 is a capacitive sensor 596 and thus the displacement of the first movable portion 552 causes one of the capacitances to change, which is sensed by the capacitive sensor 596. This change can be used to detect the displacement of the first movable portion 552, such as in Figure 6B. The 5H displacement may indicate a pressure change or pressure experienced within the evaluation chamber 546 and may generate a signal or be displayed on an indicator 562. In general, the capacitance between the first movable portion 552 and the capacitive sensor 596 is proportional to the square of the distance between them. Referring now primarily to Figures 7A and 7B, a portion of a non-limiting embodiment of a reduced-pressure evaluation subsystem 6〇8 is presented. The reduced pressure evaluation subsystem 608 includes a delta ration chamber 646 showing that a portion of the evaluation chamber has a wall 65 〇. Wall 650 includes a first movable portion 652.

The first partition 054 can include a target 655' target 655 having a flexible or semi-flexible knife 657 that couples the target 655 to the wall 650. The flexible or semi-flexible portion 657 allows movement of the target 655. Under depressurization, the first movable portion 652 is moved inwardly from a neutral position to a displacement position into the evaluation chamber 646 as shown in Fig. 7A. 156368.doc -18 - 201200178 A first pressure detector 658 is fluidly separated from the evaluation chamber 646 and substantially aligned with the first movable portion 652. The first pressure detector 658 can be internal to an isolation chamber 660. In this embodiment, the first pressure detector 658 is an ultrasonic sensor 697 that emits ultrasonic waves that are ejected from one of the reflectors 691 on the first movable portion 652. The ultrasonic sensor 697 senses the displacement of the _ movable portion 652 and generates a signal indicative of the displacement. This signal can be used to display a pressure measurement on an indicator 662 or for further processing. Referring now primarily to Figures 8A and 8B, another illustrative, non-limiting embodiment of a portion of a reduced pressure evaluation subsystem 7 (10) is presented. The reduced pressure evaluation subsystem 708 includes an evaluation chamber 746 that is partially displayed. The evaluation room 7 privately includes a wall 75 具有 having a first movable portion 752. The first movable portion 752 can be a first partition 7 Μ β first partition? 54 may include a target 755 and a flexible or semi-flexible portion 757. The first movable portion 752 moves under reduced pressure and is movable from the neutral position to the displacement position into the evaluation chamber 746. A first pressure detector 758 can be located proximate to the first moveable portion 752 and fluidly isolated from the interior of the evaluation chamber 746. The first pressure detector 758 can be included in an isolation chamber 760. In this illustrative, non-limiting embodiment, isolation chamber 760 includes a window 76 window 761 that allows at least infrared signals to travel through. The first pressure detector 758 includes an infrared sensor 798 that is operable to propagate an infrared wave through the window 761 to affect the first movable portion 752 and determine the relative position of the first movable portion 752. The first movable portion 752 reflects the infrared wave.
